How can I programmatically get the phone number of the device that is running my android app?
Code:
TelephonyManager tMgr = (TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE);
String mPhoneNumber = tMgr.getLine1Number();
Required Permission:
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
According to the highly upvoted comments, there are a few caveats to be aware of. This can return null
or ""
or even "???????"
, and it can return a stale phone number that is no longer valid. If you want something that uniquely identifies the device, you should use getDeviceId()
instead.
